Beit known that We, WILLIAM E. MOORE end Jos m'n H, Hunnl mx both citizens of the United States aml residents of Wgusan Junction, in the county of Marathon and State (if-Wisconsin, enilof lfilend, in the count; of ShaiWaLnQ fend vState of w isconsin, pe e y useful Improvements in S cree i- Sa, ;l- 1 Lm2king Meansgvand we ,do hereby declare that the following ise full, clear, and exact de- SCPi l en th re fhe present iriventignrelates tonew and useful mprovements inzsereen structures tor windows ind incite-particularly directed to the rev ion uf n trieens for-lockinge remeveb-e emu w th n .a, .ninduw frame.

t i invention to pro'gide n -locking means 'adapted for as ,mtifl lw th sereens of an extensiblty'peto fit dilferingwidths of windows, and wherein the locking means is operative in various relative posltions ,of the screen sections, and servesto prevent telescoping movement of the seetio With the above and other objedts and edvantages in view, the invention resides more pilil'tlfilllflil'ly in the novel combination, errangement" and. jormation of parts more pertieulnrly hereinafter described and more claim -In the drawings;

l igur'e 1 is 1 side elevntional view of an extension screen disposed in a window frnine and with thei'n'ip'roved locking means associated therewith, this view being telren sect'ionally through the window fraine'end -part1ularly poi-rifled; out the appended looking fi'om theinside. 0f the Window, as

indicated by the section line 1.1'0 Fig. 2.

Fig. 2 is a vertical seetionel view through the lower portion of the window and screen, as indicated by: the line 2 -21 of Fig. 1.

Fig. 3 is a detailed view -showin a. modified embodiment; of the iimprov loeking means associated with a} screen comprising 'esingle unitary aectionif A Re erring now .more particulerly to the have invented certain new and 9. 18 perm-(11 m an object of the the sections-will hold the screen indeed in venticnal 'znunnc r.

"For thispnrpo se,-a locking means is pmvidecl which inch: des 21 her 12 intermediateiy 1 pivoted on the imiei. face of the inner stile an to the window. k I

Pivotally seem ed as by staples 13011 the end portions of he outer edge face ottthe stiie are transv'eme pawl bars 14 which have pivot-ally conneei ed to respective ends of thelever plate 12 by links 17, End por ti ons. of the platt are projected laterally to form finger-piece: 18 and the plate is limited in its rotative mo ements by a. stop 19 on the stile. Thus upol manipulating the late, the sections may be looked against re at'i've sliding movement and may consequently by reason of their lugs 10 be locked within the window. Thus a means is provided which positively prevents manipulation of the screen from the o itside of the Window, particularly as the screen would be normally of such height as to extend substantially to theupper sash 6 to p] event a person from possibl'gwtreaching arm: 16. the top of the screen.

Fig. illustrates more broadly one of the locking features of the invention, and in this figure ascreen comprisin a single unitary section 22 is disposed in t e frame 5 and is provided at -o e end with lugs 23. similar tothe In s o one'end of the heretofore describe screen and enga cable in similar sockets 24 in one side 0 the frame. The

I other side of the frame is. provided with sockets 25 adapted to receive the projected ends of lug plates 26 which are hin ed to the adjacent stile of the screen and-a; apted to swin outwardly of the edge thereof to I engage in the said sockets. Thus the screen is inserted and locke i in. the window frame by first engaging the lugs and sockets 23 and'24 andt en when'the screen has-been positioned entireliv within the frame, swingingthe locking p ates 26 intothe sockets 25.

hat is clarified, is:

1.,The combination with a window frame prdvided with sockets in its sides, of a screen .'member including a rigid frarne and a mesh carried thereby, rigid lugs projecting'from one side of the'screen frame and engageable in the sockets of one side of the wmdow frame, and lugs movable relatively to -that portion of the screen frame carrying the said rigid lugs and engageable in the sockets of the other side of the window frame.

2. The combination with a window frame and ascreen member comprisin slidably connected rigid frame sections, 0 the sides of the window frame bein provided with sockets, lugs at the outer side frame sections engageablein said sockets,

and means for locking the screen frame secs tions against sliding movementand to the pawls.-

4.
